The Google+ project has been in field trial for just under 90 days, and in that time we’ve made 91 different improvements. Today we’re releasing nine more features that get us that much closer.

+Hangouts: more places, more people, more to do
Hangouts uses live video to bring people together, face-to-face-to-face. And from day one, the community has shaped and stretched the feature in amazing ways—from cooking classes to game shows to music concerts. We’re determined to keep this momentum going, and to keep providing new ways to communicate in-person, so we hope you enjoy this week’s round of Hangouts improvements.92.

Hangouts on your phone
In life we connect with others in all sorts of places, at all different times. And the connections you make unexpectedly are often the ones you remember the most. We think Hangouts should keep pace with how you socialize in the real-world, so today we’re launching it on the one device that’s always by your side: your mobile phone.To get started, simply find an active hangout in the Stream, and tap “Join”.Hangouts currently supports Android 2.3+ devices with front-facing cameras (and iOS support is coming soon).

Hangouts On Air:

Just start a normal hangout, and you’ll have the option to broadcast and record your session. Once you’re “On Air,” up to nine others can join your hangout (as usual), and anyone can watch your live broadcast.

Hangouts with extras:

We’re previewing some extras, including:

Screensharing: for when you want to show off your vacation photos, your high score, your lesson plan or whatever else is on your screen

Sketchpad: for when you want to draw, doodle, or just scribble together

Google Docs: for when you want to write, plan or present something with others

Named Hangouts: for when you want to join or create a public hangout about a certain topic (like fashion or music or sports…)

To start a hangout, click “Try Hangouts with extras” in the green room.

Hangouts APIs:

We’re also releasing a basic set of Hangouts APIs. If you’re a developer who wants to build new kinds of apps and games (and who-knows-what-else), then you can find more details here.

We’re bringing Google’s search expertise to Google+. Just type what you’re looking for into the Google+ search box, and we’ll return relevant people and posts, as well as popular content from around the web.

Anyone can sign up for Google+—no invitation required:

For the past 12 weeks we’ve been in field trial, and during that time we’ve listened and learned a great deal. We’re nowhere near done, but with the improvements we’ve made so far we’re ready to move from field trial to beta, and introduce open signups. This way anyone can visit google.com/+, join the project and connect with the people they care about.
